CHARLES F. BLAKELY, OF CHICAGO, ILLINOIS, ASSIGNOR OF ONE-HALF- OF HIS RIGHT TO ANSEL N. KELLOGG, OF SAME PLACE.

PRINTERS FORM.

SPECIFICATION forming part of Letters Patent No. 230,607, dated August 3, 1880.

Application filed June 25, 1878. I

To all whom it may concern:

Beit known that 1, Cinemas F. BLAKELY, of Chicago, in the county of Cook and State of Illinois, have invented certain Improvements in Printers Forms, of which the following is a specification.

This invention, which is designed to facilitate the making of changes in printers forms Without unlocking them, consists, essentially, in providing for and combining with the parts to be changed a vertical-sided socket of such height and strength as to afford proper sup port to the contiguous matter, and to be itself held in the form by the pressure from the looking, and of such interior dimensions that the removable type-blocks may be dropped in and lifted out without difficulty or binding.

In the accompanying drawings, Figure 1 is a plan of a form having one of my socketpieces locked in with the other matter. Fig. 2 is a plan of one of the sockets. Fig. 3 is a similar view with a portion of removable matter in place. Fig. 4 is a vertical central section of the socket, and Fig. 5 a side elevation of the removable block of printing matter. Fig. 6 shows another form of the removable type-block.

Like letters indicate like parts Wherever they appear.

In said drawings, A represents the chase, B the socket, and C the removable type-blocks or matter.

The sockets consist of vertical four-sided metal frames, less than type high, but of such vertical, lateral, and longitudinal dimensions and of such strength of metal that they Will give the adjoining matter and column-rules all necessary support, and as will insure their being securedin the form against any contingency by the locking. lnteriorly they conform to the shape and dimension of the removable matter they are designed to hold; but the latter, if made type high, especially when they consist of solid stereotype-blocks, need not fit very closely, as I find that they are not likely 45 to be drawn out, even if somewhat loose in the sockets. All these features will be fully understood from the drawings without further description.

My invention is also capable of use with removable type-plates less than type high and resting upon foundation-blocks permanently locked in the form; but in such case, if the Weight of the removable plates is not sufficient to secure theirretention in the form, auxiliary means must be employed to insure that result.

The'invention may also be employed in cases where the space filled by the material of the frame itself is needed for printing by making the printing-surface to extend over and cover the upper edge of the frame. This modification is illustrated in Fig.

When using stiff inks an electrotype may be used wider at the base than at the top, the inside of the frame being correspondingly inclined, as shown in dotted lines in Fig. 4.

I claim-- 1. The combination, with a printers form, of a removable type-block and a socket Wherein said block is loosely held, said socket being a vertical-sided continuous frame less than type high, of such dimensions and strength as to afford support for the contiguous matter and secure its own retention in the form by the pressure from the lockin g, and with an interior conforming to the shape and slightly larger than the block, substantially as set 'forth.

2. The socket-frame composed of'four sides,

in combination with the removable stereotype- CHAS. F. BLAKELY.
